APPARATUS FOR DRYING AND POLISHING 1DR IN-K1N G GLASS *ES.

Application filed .J' anuary '2, 1925, Serial no. .es. .Benewcdlarch '14, 1328.

The invention relates to apparatus for" drying and polishi'ng drinking glasses, or the like articles. It relates more particularly to apparatus whereby atumbler or drinking glass, or article or similar shape, may be effectively and quickly dried and polisl'1ed, by an automatic mechanism, after the article :has been washed, I

In accordance with the invention devices are provided for rotating aglass or tumbler or similar article inserted in the apparatus, the rotating article being thoroughly dried and polished :by engagementwith suitable surfaces. The rotating article preferably engages drying and polishing material which is either-stationary or is. prorid-ed with aqslow teedinglnovement, in order to remove wet portions of the same and replace them by dry portions. Preferably the drying members will engage-against the outer and inner cylindrical surfaces of the article, the inside ofthe bottom, and if desired,.the,outside ofthe bottom. a The device preferably is adapted to operate upon articles of. somewhat varying size and shape,

such ,as different forms of drinkingglass. Preferably also the machine is automatically set in operation by thelac't of placing the glass therein, so that theglass will be rotated for a suitable time interval, at the end of which time the moving parts are preferably automatically stopped.

, An object of the invention isithe provision of eflicientand comparatively simple devices of the character referred to. Other objects of the invention comprise the provision of various combinations of parts and formsof construction, allas will be more fully de scribed in the following specification and be particularly pointed out in the appended claims, l

In order that the invention may be more clearly understood attention is hereby directed to theaccompanying drawings, forming part of this application and illustrating one form of apparatus en'ibodying the in? vention. In the drawings V Fig. lrepresentsa side elevation of apparatus embodying the invention;

Fig. .2 is .a top plan view of the same;

Fig. 3 is a vertical section taken on line 3-3 of Fig. 1;

,Fig. 4 is a horizontal section taken on l ne 474,01 Fig. .1,

, cylinders 8, 8. These Fig. .5 "is an enlarged vertical section through the tumbler support with tumbler mounted thereon, and through adjacent parts, this figurebeing similar to the upper portionof Fig.3, but with the tumbler in position;

Fig. 6 .isafho'rizontal section taken on line 66 of-Fi g.,.5, and, I v

"7 is a partial vertical-section similar to the lower portion of Fig. 5, but showing the portion upon. atumbler of flaring shape.

Referring to the drawings, the apparatus as shown comprises upper and lower horizon- "tal plates or supports 1 and 2 mounted upon and supported bysnitab'le legs or vertical supports 3. I

Y A stationary tumbler or article support 4 entendsupwardly above top plate 1. This support is preferably cylindrical and may be formed of pressed metal or the like, if desired, with a top closure 5. This cylindrical supportis shown as mounted upon and extending upwardly from a plateb secured 3 upon the fixed plate 1 of the apparatus. I

A "tumbler '7 may be positioned upside I down upon support4. When so mounted the tumbler will engage a pair of rotatable c linders 8 are mounted upon or. carried y vertical spindles 8 8*,which extend downwardly through top plate '1 in which they'have journal bearin'gs, lower endsofthese spindlesbeing provided with suitable bearings on the bottomplate 2.

The tumbler when inverted over support 4 will be pressed into contact with cylinders -'8 by engagement of cylindrical support 4,

wit'h the inner surface of the tumbler at a point intermediate the cylinders 8. The

tumbler will be rotated during the drying operation by therotation of cylinders 8, which may be accomplished in various ways. Cylinders 8, inayyif desired, be provided with suitable friction surfaces.

Preferably the machine is set in operation automatically upon the insertion of the tumbler therein and the tumbler rotated for a predetermined short interval. In theconstruction shown in the drawings a=motor 9 is provided mounted uponbottoin plate 2, I this motor being connected to horizontal shaft 10 carrying worms 11, 11, which mesh with worm Jwheels 1-2, 1-2, on spindles .8

' The motor may,of course,.be ..switched on i and ofi w henflthe is placed in the apparatus, and when its drying is completed, by various forms of devices. In the form of construction illustrated a vertical rod 13 extends upwardly through tumbler support a and a short distance above top closure 5 of the support, above which rod 13 is provided with a horizontal plate 1 4, which may be of the shape indicated in Fig. 6 for a purpose subsequently to be explained. Rod 13 extends downwardly through the plates 6 and 1 and at its lower end it has a pivotal connection with arm 15 which is pivoted intermediate its ends at 16 to. a pedestal 17 extending upwardly from plate 2.

The opposite end of arm 15 is pivotally connected to a vertical plunger 18 which is movable into and out of a switch device 19. When the weight of the tumbler is placed on plate ll above ihe top of support 1 rod 13 will, of course, be depressed and plunger 18 will be moved upwardly into the switch box 15). This upward movement of plunger 18 will close contacts within box 19, which will close the motor circuit, and immediately cause the rotation of cylinders 8 and the consequent rotation of the tumbler which is engaged thereby.

' Various forms of make and break devices may be used for the switch, and it is not deemed essential to illustrate the construction of the contacts within box 19. This may be for example a switch device of the type known as a canopy switch. It is preferably provided with a form of impositive lock so that plunger 18 will remain in its upper or lower positions until it is moved therefrom.

As stated, the preferred form of the invention also includes means for automatically stopping the rotation of the cylinders 8 and-consequently of the tumbler 7 after the latter has been rotated for a desirable short time. This may suitably be accomplished by mechanism for automatically stopping the motor after a predetermined number of operations as illustrated. One of the spindles S is provided with a worm 20 which meshes with a worm wheel 21 on a horizontal shaft 22 which extends transversely across the machine and is supported by suitable brackets or pedestals 22 which extend upwardly from bottom plate 2.

Shaft 22 also provided with a cam 23. A bell crank lever having upper and lower arms 2 1 24", is pivotally mounted at 25, to support 22 and carries, at its upper end, a roller 26 which bears against the outer surface of cam 23. An arm 27 is pivotally mounted at one end at 25, the other end of this arm being pivotally connected at 28 to the plunger 18 of switch device 19. Arm 27 and the lower arm 248 of the bell crank are provided with faces which are adapted to engage as indicated at 29 Fig. 1. A

mow/s9 .plained, the arm 27 moves upwardly with plunger 18 against the pressure of spring 30. Cam 23 immediately starts rotating in a counter-clockwise direction, referring to Fig. 1, and roller 26 drops off of nose 31 of the cam whereupon the lower arm 24 of the bell crank moves upwardly a distance permitted by the engagement of roller 26' with the peripheral cylindrical surface of cam 23, and by the engagement of the coact ing faces at 29. The contacts of switch 19 accordingly remain closed during one completc rotation of cam 23 during which the tumbler which is to be dried and polished. is rotated as has beenexplained. At the end of one rotation of the cam, roller 26 will again ride out on the nose 31 of the cam, depressing the lower arm 2Q of the bell crank whereupon spring 30 pulls down arm 27 and plunger 18 to break the contacts within switch device 19 and accordingly stop the motor. 7

The devices by. which the tumbler will be dried and polished during its rotation will now be described. This is preferably accomplished. by the provision ofa pair of strips of suitable material against which the inner and outer surface of the tumbler will rub during the rotation of the latter. These strips are preferably tapes ofsuitable textile material which are passed around suitable guiding and holding means and are given suitable feeding movementaas is required, in order to present dry surfaces to the portions of the tumbler against which the bear.

One of these strips or tapes is wound around a vertical spool 33, 2," this spool being mounted on a suitable vertical spindle extending upwardly from plate 1. The tape passing off from spool 33 pasf 'cs arounda vertical roller 34 which extends upwardly from the plate (3. which is secured on the fixed plate 1 of the machine. This member 34 may take the form of a sleeve mounted upon a bolt Fig. 5. idolt 35 passes through an opening in a small horizontal plate 36, which is provided at a height slightly above the upper surfaceof the tumbler 7 when the latter is positioned on support 4-. This plate 36 may be supported. from plate 6 by vertical screws 37 or the like, Fig. 2, which may be provided with suitable shoulders or with spacing sleeves about the screws for supporting plate 3; A.

sleeve 34, as stated, and then extends for-' wardly, or towardstumbler7, for a distance, until it passes around a vertical pin 39, which extends downwardly from plate 36, see Figs. 2 and 5. The strip then extends to the left, referring to Fig.2, for a distance and passes about a second pin 39, identical with the one just referred to. The strip then extendsrearwardly, about the roller on bolt 38 and then extends off at an angle to the left, Fig. 2, and is wound upon a take-up reel 40 which extends upwardly from plate 1, parallel to the reel 33. v I

It will be noted'that tape 32 is of a width which may be approximately equal to the height of the tumbler 7, that .is, this tape may be sufficiently wide to rub against the outer cylindrical surface of the longest tumbler which will be dried. The exterior surface of the tumbler will bear-against this tape at a point intermediate the two pins 39, (see Fig. 6). Good contact between the glass and this tape 32, is insured by a leaf spring 41 which is preferably secured within tumbler support 4. The tumbler support is provided with a vertical slit through which spring 41 extends, the spring serving to press the adjacent wall of-the tumbler against the adjacent portion of strip 32, as is shown in Figs. 3 and 5. This spring also serves to press the innertape against the inside surface of the glass, as Wlll be later explained. This spring may be secured, for

example, upon a disc 42 mounted within the bottom end of the tumbler support 4.

Strip 32 may be fed forwardly upon takeup reel 40 in any suitable way, so as to provide a dry portion of the strip between pins 39, as is needful. Asis indicated in the drawings, this may be accomplished by theprovision ofa pinion 43 on one of the rotating Vertical spindles. 8

, meshes with a gear 44 mounted on a short stud extendingupwardly from plate I. A pawl 45 is mounted eccentrically on gear 44 andthe nose of this pawl engages the teeth of a ratchet 46 on the spindle of take-up reel 40. Strip 32 will accordingly be ad vanced continuously at a slow rate, and wound, up on reel 40, throughout-the rotationof the tumbler. A pawl 47 may be. provided to prevent backward motion of reel 40 and a spring 48 is indicated as connecting the tail of pawl 47 with the pawl 45, so as to maintain both pawls in engagement with ratchet 46.

The inside surfaces of the tumbler are dried by a strip of-material 49, similar to the strip 32. 'Strip 49 winds off .of-a .reel 50 which is shown, Fig. 1, as mounted beneath plate 2. The strip passe-s around a roller 51,

This pinion which extends downwardly from plate-2 at an angle of 45 degrees, so that-the tape will be directedivertically upward therefrom, as

is indicated at. 49 Figs. 1 and The tape passes around a roller '52'at the edge of upper plate and proceeds rearwardly for a short distance over plate 1, as. is indicated at'49". It'then'passes around a roller 53'and extends upwardly therefrom, as is indicated at 49 until it passes over the adjacent edge of the cap piece 14 mounted on the upper end of rod 13 within'the tunn I bler support 4. The tape passes across the top of cap piece 14, as is .indicatedfat 49",

wardly, asis indicated Fig. 31 at 49",. thence around a forty-five degreeroller' .56, from whichthe tape passes onto a take-up reel 57',

mounted on a vertical spindlezbel'ow plate; 2.

The tape portion 49 passi'ng'above cap 14 will rub against thejinner' surface of the bottom of the tumbler .7 when the latter is positioned thereon, as shown in'Fig. 5, so

that this surface, 7*, will be'dried and polished by the contact with thelstrip." The downwardly extending portion 49' of the strip wil'l'bear against the inner cylindrical surfaceof the tumbler when the latter. is po.- 1

si'tioned therein, as shown, Fig. 5, so that this surface will: be effectively dried and polished thereby. The spring 41, previously referred to, serves to. press the portion 49'. of the drying strip against the inside vertical surface ofthe glass. W'henno glass is in position'to be operated upon,'thepoi'ti on49"" of the strip 49 willextend somewhat at an angle from the upper edge of cap piece 14 to'the roller 54, asis indicated-in Fig. 3, in

which position it will bear somewhat against the adjacent poi'ztion of the outer drying strip 32 extending between pins. 39, 39. When the tmnbler'is inserte'dinposition for drying, it will press; apart the drying'strips 32 and 49, and will talte a position between them, engaged on the inner and outer sides by strips 49 and sans is indicated in Tape or strip 49 is fed onto the take-up reel 57 during the rotation of the tumbler by suitable means, such as a pawl 58 which coacts with a ratchet 59 on theshaftof take-up; reel 57. The construction of the feeding devices" for this strip may, as illus- I trated. be the. same as thos e for the othe'r strip 32. 'Ihat'is,"asv'shown, pawl 58 may be mo'untedeccentrically upon a gear 59 which meshes with a 'plnionffifldn the spindle of theright-hand IOtating cylinder 8,

Fig. 2. A pawl 61 is also indicated for preventing return motionof ratchet 59 and a spring 62 is indicated as connecting the tail of pawl 61 with the pawl 58 so as to keep both .pawls in engagement with the ratchet.

Means for drying and polishing the outer bottom surface of the tumbler may be provided, if desired. This may take the form of a drying member 63, pivotally mounted at 64 to a bracket on plate 36. This mcmber may be swung back out of the way, as shown in Fig. 3, until a tumbler is in position to be dried, whereupon member 63 may be swung downwardly intothe engaging position shown in Fig.v 5.

It will. be noted that the vertical pins 39 about which tape 32 extends preferably extend downwardly for a distance considerably less than the height of the tumbler. With this arrangement strip ?2 will engage against the entire length of a cylindrical or tapered tumbler positioned in place, as shown in Fig. 5, pins 39 being of a length sufficient to provide enough bearing for strip 32 for this purpose. If, however,a tumbler 7 having an outwardly curved lower end be inserted in the apparatus, as is indicated in Fig. 7, in this case the outer strip 82 and the inner strip 49 will both be able to lie against the curved lower surface of the inverted tumbler. In this case the pins 39 will hold the outer strip 32 in firm contact with the straight portion of the tumbler, while the curved portion of the tumbler below pins 39wvill cause the downwardly extending portion of strip 49, before the latter passes over roller 54:, to follow and press against the inner curved surface of the tumbler. The outer strip 32 will be pressed backwardly a sufficient amount by the belled portion of the tumbler below pins 39 but will continue to bear against this portion of the tumbler.

. It is believed that it willbe clear from the above that the various surfaces of the tumbler will be'effectively dried and polished and provided with a high polish, by the action of the variousfldrying surfaces described, during the interval of time through which the tumbler is rotated.
